One exhibit that holds great interest for ancient nomadic military art researchers is the bronze helmet on display in our museum. This particular helmet is the last of four related helmets found in Mongolia that have been recorded. It was made using bronze melting technology and has a neck protection edge at the back. The top of the helmet is circular but elongated longitudinally from front to back, with a loop on the top measuring 14 cm in length and 4.4 cm in width. The loop is circular, 1.1 cm in height, and 0.5 cm thick, with a vertical semi-circular shape in the front. It serves as protection against beetles. The helmet's round part protects the upper part of the wearer's eyes with a thick edge. A vertical triangle with a sharp edge runs from the tip of the beetle guard to the top loop. The lower part of the helmet is straight, and holes measure 0.5-0.6 mm in size and 1 cm apart to attach the neck guard. This helmet was found in Bat-Ulzii Sum, Khyatruun Range, Overkhangai Province.
